There was a problem hiding this comment.
if you could flip this out to an strnlen using the remainder of the buffer to be examined as the size I'll happily accept this.
The LoadLibrary calls should also have a matching FreeLibrary call. Msg should call out unable to load kernel32, granted if this bof started running kernel32 should already be loaded in.

This is basically a clone of the
